Marmot has several flavors of the lightweight Precip rain jacket/anorak on sale, and probably some other useful stuff. 10% Activejunky cash back as well.
I've gotten several pairs of Marmot Precip on Sierra Trading for around $50 each for tops and bottoms. The tops are super light and shed water pretty darn well. I used them again this weekend while sheep scouting. They are a tad lighter weight than my Sitka raingear. Love the pitzips on the jackets!
